Apache 无法传输项目：未解释settings.xml属性

我正在尝试基于以下项目构建gitlab ci：

• 位于nexus存储库上的父pom（不是父目录）
• 使用settings.xml中的

  maven.repo.url

  属性集

当将

${maven.repo.url}/public

中的

repositories.repository.url

条目替换为硬编码的url（例如

http://localhost:8081/nexus/content/repositories/public

。但是，当尝试使用settings.xml中的属性集时，生成错误会：

无法将项目mygroup:myparent:1.0-SNAPSHOT从/传输到myrepo（${maven.repo.url}/public）

.gitlab-ci.yml

.m2/settings.xml（注意：我在GitLab组变量中设置了

MAVEN\u REPO\u URL

）

我的个人资料
真的
${env.MAVEN\u REPO\u URL}

pom.xml

4.0.0
mygroup
我的父母
1.0-快照
我的神器
我的名字
1.0-快照
粘液
nexus存储库
${maven.repo.url}/public

我希望我能够在pom.xml中使用

maven.repo.url

属性，就像我在pom.xml中的其他地方一样。它可以很好地下拉依赖项，但无法从远程nexus存储库中下拉父pom

以下是maven错误消息：

我发现需要启用快照存储库，以便下载父pom快照。以下是更新后的.m2/settings.xml文件：

我的个人资料
表示默认情况下已启用快照

我发现了这一点，为我指明了正确的方向。
你确定你的存储库URL是正确的吗？如果是这样的话，那可能是一个bug，因为存储库URL应该是正确的，因为使用相同的变量来正确地下拉所有依赖项@克里斯涅夫
